Cloud Native Architectures

Overview of this book

Cloud computing has proven to be the most revolutionary IT development since virtualization. Cloud native architectures give you the benefit of more flexibility over legacy systems. To harness this, businesses need to refresh their development models and architectures when they find they don’t port to the cloud. Cloud Native Architectures demonstrates three essential components of deploying modern cloud native architectures: organizational transformation, deployment modernization, and cloud native architecture patterns. This book starts with a quick introduction to cloud native architectures that are used as a base to define and explain what cloud native architecture is and is not. You will learn what a cloud adoption framework looks like and develop cloud native architectures using microservices and serverless computing as design principles. You’ll then explore the major pillars of cloud native design including scalability, cost optimization, security, and ways to achieve operational excellence. In the concluding chapters, you will also learn about various public cloud architectures ranging from AWS and Azure to the Google Cloud Platform. By the end of this book, you will have learned the techniques to adopt cloud native architectures that meet your business requirements. You will also understand the future trends and expectations of cloud providers.

Patterns for moving off monolithic application architectures to AWS native architectures

In the earlier sections, we discussed multiple options to create greenfield cloud-native applications using various AWS services. That part is a little easy, as you are starting fresh and so you can use various cloud services as you architect your solutions. However, if you have a huge technical debt in an on-premise environment and want to reduce that by moving over to a cloud platform such as AWS, then it takes more effort and planning.

In recent years, AWS has matured its migration services, methodology, and messaging to make it easier for organizations to not just think of greenfield but even plan for brownfield implementations in AWS. They have a methodology of the 6Rs, which possibly covers every scenario for any workload migration to AWS. The 6Rs that AWS has are Rehosting, Replatforming, Repurchasing, Refactoring/Re-Architecting, Retire, and Retain.

The following is a snapshot of this methodology...
